It seem to me, Magnifica that label from Africa are more likely to be Red base (certainly not all of them) All of the Red based anemones I ever have, if there is a location of origin associated with it, it's Africa. Also they seem to have shorter more blunted tentacles than elsewhere in the Pacific.
I wonder if other Magnifica keepers confirm this. Information like this is not reliable, unless confirm by a vendor who handle a lot of Magnifica.
